Application of the maximum algorithm to the lipkin model

  • 28 Accesses


Lipkin constructed a many-Fermion system which, despite the simplicity of its Hamiltonian, exhibits features of complex systems. Application of the maximum algorithm is attempted in order to find the ground-state level. Numerical computations suggest that eigenstates of a particular parity transformation introduced by Lipkin have many advantages. Coupling of two models provides a means of studying the maximum method in the product space generated by the two subsystems.
